I. ihame ryo guhimba LCD
Amazi ya kirisiti
Mugaragaza isa na ecran imwe gusa, mubyukuri, igizwe ahanini nibice bine binini (filter, polarizer, ikirahure, itara rya cathode fluorescent itara), hano kugirango tuguhe ibisobanuro bigufi.
Akayunguruzo: impanvu ituma TFT LCD ishobora kubyara amabara ihinduka cyane cyane uhereye kumashusho.Ikintu cyitwa flux kristal paneli gishobora gutuma molekile ya kirisiti ihagaze kumurongo binyuze mumihindagurikire ya voltage yo gutwara IC, kugirango yerekane ishusho.Ishusho ubwayo ni umukara n'umweru, kandi irashobora guhinduka muburyo bw'amabara binyuze muyungurura.
Isahani ya polarisiyasi: isahani ya polarize irashobora guhindura urumuri rusanzwe mubintu byumurongo wa polarisiyonike, imikorere yayo nugutandukanya urumuri rwumurongo winjira hamwe nibice bya polarisiyasi, igice kimwe nukugikora, ikindi gice nukwinjira, gutekereza, gutatanya nizindi ngaruka zo kubikora byihishe, gabanya ibisekuru byumucyo / bibi.
Itara rikonje rya cathode fluorescent: rirangwa nubunini buto, urumuri rwinshi nubuzima burebure.Bukozwe mubirahuri byabugenewe kandi bitunganijwe, amatara akonje ya cathode fluorescent arashobora gukoreshwa inshuro nyinshi nyuma yo gucana vuba kandi birashobora kwihanganira ibikorwa bigera kuri 30.000.Kubera ubukonje bwa cathode fluorescent itara UKORESHEJE ifu ya fosifori y'amabara atatu, bityo ubukana bwayo bwiyongera, kugabanuka k'umucyo kugabanuka, imikorere yubushyuhe bwamabara nibyiza, bityo bikabyara ubushyuhe buke cyane, bikarinda neza kristu yacu ya kirisiti yerekana ubuzima.
Impamvu no gukumira ibibanza byiza / bibi bya kirisiti
1. Impamvu zuwabikoze:
Ikibanza cyiza / kibi kizwi kandi nk'ahantu heza ha LCD, ni ubwoko bwangirika bwa LCD.Biterwa ahanini no gukomeretsa imbaraga zo hanze cyangwa guhindura bike isahani yimbere yimbere yikibanza cyiza.
Buri pigiseli kuri ecran ya LCD ifite amabara atatu yibanze, umutuku, icyatsi nubururu, bihuza kubyara amabara atandukanye. Fata LCD ya santimetero 15 nkurugero, agace kayo ka LCD ni 304.1mm * 228.1mm, gukemura ni 1024 * 768, kandi buri pigiseli ya LCD igizwe nigice cyambere cyamabara ya RGB. Pisikeli y'amazi ya kirisiti ni "agasanduku k'amazi ya kirisiti" yakozwe mugusuka kristu y'amazi muburyo butajegajega.Umubare wibyo "bisanduku byamazi ya kirisiti" kuri ecran ya 15 ya LCD ni 1024 * 768 * 3 = miliyoni 2.35! Ubunini bwakazu ka LCD bungana iki? Turashobora kubara byoroshye: uburebure = 0.297mm, ubugari = 0.297 / 3 = 0.099mm! Muyandi magambo, miliyoni 2.35 "agasanduku k'amazi ya kirisiti" ifite ubuso bwa 0.297mm * 0.099mm gusa itunganijwe cyane munsi yubuso bwa 304.1mm * 228.1mm, kandi umuyoboro utwara ibinyabiziga utwara agasanduku kameze neza. inyuma yisanduku ya kirisiti isukuye. Biragaragara, uburyo bwo gukora ibisabwa kumurongo wumurongo ni mwinshi cyane, kubuhanga bugezweho nubukorikori, ntibishobora kandi kwemeza ko buri cyiciro cyakozwe na LCD ecran itagaragara / ingingo mbi, abayikora muri rusange birinda ibintu byiza / bibi kuri igice LCD panel, ntamwanya uhari / mubi cyangwa ahantu hake cyane / ahantu habi cyane LCD yumurongo utanga amasoko menshi yinganda zikomeye, kandi urumuri / ingingo mbi cyane ecran ya LCD mubisanzwe ni bike bitanga ibicuruzwa bito mu bicuruzwa bya LCD bihendutse.
Muburyo bwa tekiniki, ikibanza cyiza / kibi ni pigiseli idasubirwaho kumwanya wa LCD ikorwa mugihe cyo gukora.Ikibaho cya LCD kigizwe na pigiseli isukuye ya kirisiti, buri kimwekimwe gifite tristoriste eshatu zihuye nayunguruzo rutukura, icyatsi nubururu inyuma ya a 0.099mm y'amazi ya kirisiti ya pigiseli
Transistor ikosa cyangwa umuzunguruko mugufi ituma iyi pigiseli iba nziza / mbi.Iyongeyeho, buri pigiseli ya LCD nayo ihuriweho inyuma ya tariyeri itandukanye kugirango uyitware.Niba rimwe cyangwa byinshi byamabara atukura, icyatsi nubururu byananiranye, pigiseli ntishobora guhindura ibara kandi izahinduka ibara rihamye, bizagaragara neza mumabara amwe.Nibintu byiza / bibi bya LCD.Uburyo / bubi ni ubwoko bwangirika bwumubiri budashobora kwirindwa 100% mugukora no gukoresha ecran ya LCD.Mubihe byinshi, bikozwe mubikorwa byo gukora ecran.Mu gihe cyose rimwe cyangwa byinshi byamabara yibanze agize pigiseli imwe byangiritse, ibibara byiza / bibi bibyara umusaruro, kandi umusaruro nogukoresha birashoboka ko byangiza.
Nkuko amasezerano mpuzamahanga abigaragaza, kwerekana kristu yerekana ibintu 3 munsi yumucyo / mubi biri murwego rwemewe, icyakora umuguzi ntabwo ashobora kuba yiteguye kugura monite ifite ingingo nziza / mbi mugihe uguze kristu yamazi, bityo uruganda rukora ibintu bya kirisiti ibyo bifite ingingo nziza / mbi mubisanzwe igurisha cyane.Ni gute abakora panel bakorana nibice bitatu cyangwa byinshi byiza / bibi bitewe nuburyo bwo gukora? Kugirango babone inyungu, ababikora bamwe ntibazasenya izo ecran za LCD, kandi mubihe byinshi, bo Azakoresha ibikoresho byumwuga kugirango avure ahantu habi / habi, kugirango agere ku ngaruka zo kutagira ibibi / bibi ku buso ku jisho ryonyine.Abakora inganda nke ntibanakora no gutunganya, shyira mu buryo butaziguye ibyo bikoresho mu murongo w’ibikorwa kubyara umusaruro, kugirango ugere ku ntego yo kugabanya ibiciro.Ubu bwoko bwibicuruzwa bufite akarusho kubiciro, ariko bizatanga ahantu hakeye / habi nyuma yo gukoreshwa. Kugeza ubu ku isoko ibintu byinshi bihendutse byamazi ya kirisiti ni byogutunganyirizwa hanze, ntushaka rero kugura ibintu byamazi ya kirisiti yerekana bihendutse, kugura ibicuruzwa bimwe bitazwi. Nishimiye kugura igiciro gito - cyigiciro kitari - cyerekana neza.Kuko nyuma yigihe gito, ibintu udashaka kubona amaherezo bishobora kubaho.
2. Impamvu zo gukoresha
Ingingo zimwe za LCD nziza / mbi zishobora guterwa no gukoresha inzira, gusa nkubwire kubyerekeye gukoresha bisanzwe uburyo bwo kwirinda:
(1) ntugashyireho sisitemu nyinshi icyarimwe; Kwinjiza sisitemu nyinshi murwego rwo guhinduranya bizatera urwego runaka rwangirika kuri LCD.
(2) kugumana voltage n'imbaraga bisanzwe;
(3) ntukore kuri buto ya LCD umwanya uwariwo wose.
Izi ngingo uko ari eshatu zigira ingaruka zitaziguye cyangwa zitaziguye ku mikorere isanzwe ya molekile ya "lisiti ya kristu yisukuye", ishobora kuganisha ku musaruro wibintu byiza / bibi.Mu byukuri, ahantu heza / habi h’abaguzi mugikorwa cyo gukoresha harashobora kumvikana binyuze mu igenzura rya ba injeniyeri.Ndetse ahantu heza / habi h’abaguzi harashobora kumvikana niba ababikora batagiriye nabi abaguzi nta mutimanama.
Igipimo cyigihugu ni 335, bisobanura ahantu hatatu, cyangwa ibibara bitatu byijimye, byujuje ibisabwa.
